Name: A.1264
Reference: EcoArt 2002
Description: These mesic subalpine grasslands occur on a narrow elevational band (3250-3450 m) on the White River Plateau. Sites are gentle toeslopes and on slopes bordering upland benches. The landscape relief is most often concave which lends itself to favorable soil moisture conditions despite the southerly aspects preferred by this community. Stands have a moderately dense herbaceous layer dominated by ~Poa nervosa$ and ~Achnatherum lettermanii (= Stipa lettermanii)$. Associated graminoid species include ~Festuca brachyphylla, Phleum alpinum, Poa fendleriana$, and ~Trisetum spicatum$. There may be sparse to moderately dense cover of forbs such as ~Achillea millefolium var. occidentalis (= Achillea lanulosa), Agoseris glauca, Erigeron peregrinus, Erigeron simplex, Hymenoxys hoopesii (= Helenium hoopesii), Polygonum bistortoides, Packera crocata (= Senecio crocatus)$, and ~Viola nuttallii$.
